Abstract :
For textile products, we are required to display the name of the composition fiber with a percentage of the mix to protect the benefits of customers. The present inspection method is based on JIS L 1030-1,2. However this method is destructive inspection and takes a lot of time. To solve these problems, we study non destructive inspection method by infrared absorption features. This time, to become practical, we tried to improve the accuracy of mixed rate prediction. As a result, it was confirmed the possibility of improving the accuracy of mixed rate prediction by normalization in the isosbestic point.
